    Sammanfattning : Since the isolation of graphene in 2004, much research has been conducted to understand this novel material and how its properties can be utilized in different applications. One type of venture involves graphene as a reinforcing filler in metal matrix composites (MMC) which is becoming increasingly prevalent in the automotive and aerospace industries. LÄS MER

  3. 17. A Study on Desulfurization of Hot Metal Using Different Agents

    Författare :David Lindström; Du Sichen; Nortier Patrice; Shin-ya Kitamura; KTH; []
    Nyckelord :desulfurization; hot metal; CaO; Mg; CaC2; ZnO; reaction mechanism; desulfurization abilities; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : This thesis deals with desulfurization of hot metal using different agents. The aim of this study was to improve the understanding of commonly used desulfurization agents such as fluidized CaO, CaC2, commercial-CaO, Mg, and mixtures of commercial-CaO-Mg. The possibility to use ZnO for desulfurization of hot metal was also investigated. LÄS MER

  4. 18. Characteristic Properties and Applications of Fine Particles in Biomass Gasification

    Författare :Azhar Malik; Ergonomi och aerosolteknologi; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Gasification; Biomass; Fine particles; catalyst deactivation; dilution probe sampling; organic;

    Sammanfattning : The gasification of biomass is a promising route to increase the share of renewable sources in the energy mix. Besides having an overall higher thermal efficiency than combustion, it also offers the possibility of producing gaseous and liquid biofuels that can be used in the transport sector. LÄS MER

  5. 19. Raman and Fluorescence Spectroscopy of Single Molecules and Metal Particles

    Författare :Jerk Bjerneld; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; laser-induced; single-molecule spectroscopy; surface-enhanced Raman scattering; nanoparticles;

    Sammanfattning : Technological and conceptual advances have led to the realization of single-molecule spectroscopy. This permit detailed investigations of heterogeneous systems in fields ranging from condensed matter physics to biochemistry. It was recently discovered that surface-enhanced Raman scattering (SERS) can be used to study single molecules. LÄS MER
